Crystal structure determination, Hirshfeld surface analysis and energy frameworks of 6-phenyl­sulfonyl-6H-thieno[3,2-c]carbazole

In the title compound, C(20)H(13)NO(2)S(2), the carbazole ring system forms a dihedral angle of 89.08 (1)° with the sulfonyl-substituted phenyl ring. Intra­molecular C—H⋯O hydrogen bonds involving the sulfone O atoms and the carbazole moiety result in two S(6) rings. In the crystal, mol­ecules are linked via pairs of C—H⋯O hydrogen bonds forming inversion dimers with an R (2) (2)(12) graph-set motif. Analysis of the Hirshfeld surfaces and two-dimensional fingerprint plots was used to explore the distribution of weak inter­molecular inter­actions in the crystal structure.
